I hope too that there is a "check-box" for this for all maps, but in V9 version, the throttle table has been revisited and built-in.
Oh? That's very good news to me indeed. I'm running V7 so i'll give V9 a try when it warms up!

Probably because Anti lag would place more strain on the turbos and engine then without, OTS maps are designed to be Conservative, relatively safe.

I understand this, i'm just stating they offer it as an option on N55F, S55, & N13, but not the N54. There are still plenty of people on upgraded twins and single who run MHD that would most likely benefit from the feature

Anti lag is an option on N55 ots maps?

Upgraded twins or singles should be running custom maps, ots maps not designed for them though,

Yes, N55 F chassis have anti-lag as an option on MHD OTS maps now. They even have the option to set the boost target for anti-lag.



Edit: Also i'd like to clarify when I said upgraded and single people run MHD i'm referring to custom tunes through MHD. You can still use some of MHDs features with a custom tune such as launch control.

Hopefully. I'm not an expert on this by any means and am absolutely not a tuner however I wonder if the reason we don't yet is our DMEs. That update was for MEVD DMEs which presumably have different capabilities than ours, however this is just speculation on my part as I know flashable anti-lag is already possible on the N54, you just have to do some wiring for the button lol

Any updates on this true 1m throttle table on MHD ?? I see there’s s v10 closed beta right now that logs look good but hope there’s a 1m throttle toggle. Could anyone comment on the revised throttle mapping on v9 compared to the older ones??

I tried the v9 map, found the throttle more progressive, went back to v7.1 as I prefer boost to build up faster lower down and more snappy throttle.

V9 seemed to have higher boost but lower ignition timing per cylinder than v7,

Got about 5 degrees on V9 vs 8 degrees on V7.1,

V9 runs fine though, just a matter of preference.

Interesting, thank you for the perspective. Are you running linear throttle mapping toggle?

Are you trying to say v7 is more aggressive on the motor & timing compared to v9?

No linear throttle mapping here, linear throttle mapping doesn't run well on a Auto in my opinion, I can see it suiting a Manual transmission though.

I'm saying v7.1 targets lower boost than v9, but it builds the boost quicker with more timing.

V9 on the other hand has higher boost target but seems to have less ignition timing, builds boost more progressively.

Matter of preference to be honest, I prefer v7.1

Guys, is it possible to change those tables on my E90 N55? I’d like to zero them all out! 😈
I just hate the sluggish throttle response as it is.
I’m currently running on MHD Stage 2, so will I need a custom tune to change them?
